This map shows the index values which represent the ratio of the rural population and
urban population. Higher the index value more is the rural population and thus that
area is more prone to out migration triggered by rainfall.
This map shows location of water bodies .Blue colored features shows the water
bodies. Data capture time was 2005. The districts having water bodies will be less
affected by variation in rainfall.
The table shows the population collected for all the districts of Andhra Pradesh
This table shows rainfall values collected in mm for each district from 1991-2001.
This data will be used to find the areas which have faced unusual rainfall patterns
which might have led to migration.
This map shows rainfall profile over 11 years(1991-2001) for each district of Andhra Pradesh
Rainfall profile of Guntur
Rainfall profile of Adilabad
These graphs shows that Adilabad has faced less variation about mean
rainfall and thus might have experienced less migration. The combination
with other factors will tell us the final picture. Values are in mm.
This map shows standard deviation in rainfall which very well captures the variability in
rainfall. High variability is undesirable for cultivation so by this map it can be inferred that
upper region of Andhra Pradesh has more rainfall than coastal regions.
This map shows soil pattern of the state. This has been considered because soil type
decide the water requirement of the land and thus can influence migration as soil with
less requirement may survive less rainfall condition.
This map shows water holding capacity of the soils of Andhra Pradesh. High water
holding capacity can help in good sustenance of crops in case of less rainfall.
Relative Migration
• Because of lack of exact data regarding
population growth and migration, new index
has been introduced.
• RM= (% population in 2001 - % population in 1991)/%population in 1991
• It shows the relative movement of population
within the state based on it’s previous
population assuming constant growth rate for
each district.
Relative migration for each district (darker color shows higher inmigration)
This map shows the general trend in migration. People are migrating from
coastal and lower regions to upper region of Andhra Pradesh.
Districts not following the general trend
Questions addressed
• We are going to answer why general trend has
appeared?
• Explaining the reasons for the
outliers(vishakhapatnam and kurnool)
• These will be answered based on the rainfall,
rice cultivation , rural-urban index and soil
data.
Reasons for General Trend
• Rural-Urban Index is low in upper region of
Andhra Pradesh, so upper region is less
affected by variation in rainfall.
• The standard deviation in rainfall in upper
region is very less as compared to lower
region of Andhra Pradesh, which means that
the upper region witnessed less variation in
rainfall. Hence it was more suitable for
cultivation.
Reasons for General Trend
• The water holding capacity of the upper
region was good as compared to coastal
regions.
Reasons for Outliers
• Kurnool and Vishakhapatnam have less RuralUrban Index as compared to their neighboring
districts.
• District near Vishakhapatnam(Srikakulam and
Vizianagaram) have high Rural-Urban Index and
high percentage of rice fallows.Moreover the
water holding capacity in these districts is less
which would have made cultivation unsuitable.
Vishakhapatnam having low Rural-Urban Index
must have provided employment opportunities.
